· Product Overview
This set of precision-engineered barrel nuts (also known as cross dowel nuts) are custom CNC-machined components manufactured from high-grade stainless steel, designed for reliable right-angle fastening and secure assembly applications. Featuring a robust cylindrical structure, a slotted drive head for easy installation, and a precision-machined radial threaded hole (or through-hole for pin applications), these fasteners deliver exceptional tensile strength, corrosion resistance, and dimensional consistency. Available in multiple standardized and custom sizes, they provide a durable, high-performance fastening solution for furniture manufacturing, industrial machinery assembly, and custom fabrication projects.
· Core Specifications
| Specification | Details |
|---|---|
| Base Material | 304 Stainless Steel (standard); 316 Stainless Steel (marine-grade corrosion upgrade); customizable to carbon steel, brass, or aluminum |
| Surface Finish | Precision-machined to Ra ≤ 1.6μm, with standard passivation for enhanced rust resistance; optional electropolishing, zinc plating, or black oxide coating available |
| Dimensional Tolerance | ±0.01mm for critical thread pitch and outer diameter; ±0.02mm for overall length; compliant with ISO 2768-m and ISO 965 thread standards |
| Core Machining Processes | CNC precision turning, slot milling, radial drilling, precision tapping, and chamfering |
| Key Features | Integrated slotted drive head for simple wrench-free installation, precision radial threaded hole for right-angle fastening, uniform cylindrical profile for stable fit, burr-free threads for smooth assembly |
· Application Scenarios
These stainless steel barrel nuts are ideally suited for a wide range of industrial and commercial applications, including:
- Furniture Manufacturing: As core fasteners for flat-pack furniture, cabinetry, wardrobes, bed frames, and custom woodworking projects
- Industrial Machinery & Automation: For secure right-angle assembly of equipment frames, robotic components, and automated production line fixtures
- Automotive & Transportation: For interior trim fastening, custom vehicle modifications, and aftermarket component assembly
- Electronics & Enclosures: For mounting and assembly of server racks, electronic enclosures, and industrial control panels
- Marine & Outdoor Equipment: Marine-grade 316 stainless steel variants for corrosion-resistant fastening in boat building, outdoor furniture, and coastal infrastructure
- DIY & Custom Fabrication: For hobbyist projects, custom metalwork, and prototype assembly
· Production Process Introduction
- Design & Engineering Validation: Our professional engineering team collaborates with you to review CAD drawings, optimize thread fit and dimensional specifications, and ensure the design meets your assembly and load-bearing requirements.
- Raw Material Preparation: Premium stainless steel bar stock is sourced from certified suppliers, with full spectrometric analysis conducted to verify material composition, purity, and mechanical properties.
- CNC Precision Turning: High-speed CNC lathes machine the cylindrical blank to exact outer diameter and length specifications, with chamfered edges for safe handling and easy installation.
- Secondary Machining Operations: Precision milling creates the slotted drive head, while radial drilling and tapping form the internal threaded hole (or through-hole) to exact thread standards.
- Deburring & Finishing: All components undergo meticulous deburring to ensure burr-free threads and smooth surfaces, eliminating the risk of cross-threading or damage to mating parts during assembly.
- Comprehensive Quality Inspection: 100% inspection is performed for every part, including thread verification with go/no-go gauges, dimensional measurement via CMM (Coordinate Measuring Machine), and visual inspection to ensure compliance with all specifications.
- Final Packaging Preparation: Components are cleaned, sorted by size, and prepared for packaging in a controlled environment to prevent contamination and surface damage.
· Packaging and Shipping Methods
- Standard Packaging: Each fastener is sorted by size and placed in custom EPE foam trays to prevent tangling and surface damage. Bulk orders are packed in heavy-duty corrugated cartons with reinforced edges, with additional cushioning to ensure protection during long-distance transit.
- Shipping Options:
- Express Delivery (3-7 Business Days): DHL, FedEx, or UPS for prototypes, small batch orders, or urgent requirements, with full tracking and delivery confirmation provided.
- Standard Sea Freight (25-40 Business Days): Cost-effective FCL/LCL options for large-volume production orders, with full customs documentation and logistics support included.
- Custom Packaging Solutions: We offer fully customizable packaging, including branded labeling, barcoding, serialized part marking, and custom size sorting to align with your inventory management and brand guidelines.

· Frequently Asked Questions (FAQ)
What is your Minimum Order Quantity (MOQ)?
Our MOQ is highly flexible to support your business needs: we accept orders starting from 1 piece for prototyping and custom one-off projects, with tiered volume pricing available for production runs starting at 100 pieces. We specialize in both low-volume, high-mix custom manufacturing and large-scale OEM production.
What are your typical lead times?
- Prototyping: 5-10 business days from final design approval to shipment.
- Mass Production: 10-25 business days, varying based on order volume, design complexity, and custom surface treatment requirements.
- Rush Service: Expedited production (3-5 days for prototypes) is available upon request for an additional fee.
Can you accommodate custom modifications and designs?
Absolutely. We offer full end-to-end customization to meet your exact application requirements:
- Material Customization: Alternative materials including 316 stainless steel, carbon steel, brass, and aluminum for specialized strength, corrosion resistance, or cost requirements.
- Design Modifications: Custom thread sizes (metric/imperial), length and diameter adjustments, custom drive features (hex socket, Phillips head), or additional through-holes and slots.
- Surface Finish Options: Custom electropolishing, plating, passivation, or coating to enhance corrosion resistance, wear performance, or aesthetic appeal.
- Branding & Traceability: Laser engraving of part numbers, logos, or serial numbers for full product traceability.
